Stenlakes provide turnkey solutions for the design and installation of new utility lines, using precision laser levelling and GPS mapping for entire projects. We offer a multitude of installation techniques from open cut to trenchless, including chain trenching, vibratory mole ploughing, thrust moling and horizontal directional drilling. We also provide excavator mounted screening for backfill and bedding of utility trenches in rocky soils, without the need to import sand or remove excess spoil.

We offer concrete pouring services for foundations, roadways and highway base layers and construction of pre-formed concrete structures.

For road crossings we prefer to employ trenchless techniques, which enable the installation of ducts, pipes or cables, without disturbing the surface or integrity of the road.
